I'm working on a device driver for an IDE controller card and I'm having problems putting a filesystem on the drive. I want to make sure that the driver isn't corrupting data so I wrote a short perl script which generates random sized blocks of data, writes it to the disk, then reads it back. How can I disable disk caching so that I know the data I read back and compare to the original data is actually from the drive and not the disk cache?
